Technology / Wall system

The concrete wall system, built by robotic construction.

Titan and FormCrete are technologies of ICON.

ICON describes its 3D-printed concrete wall system as an engineered, load-bearing wall assembly combining printed concrete shells, reinforced structural cores, insulation and integrated pathways for building systems.

01 / Wall assembly

A defined assembly, reviewed in context.

The component language for this wall assembly is limited to ICON's description: printed concrete shells, reinforced structural cores, insulation and integrated pathways for building systems.

3D printing is the familiar term for additive concrete construction.

Figures published by ICON.

These are ICON-published capabilities, not guaranteed Layered Construction outcomes. Actual pricing, staffing, production and schedules depend on the design, location, site conditions, engineering and scope of the project.

Technical performance depends on the exact wall assembly, material, reinforcement, engineering and project conditions. Final designs require review and approval by the applicable engineers, design professionals and code officials.

03 / Technical credentials

Published credentials, project-specific review.

01ICON's wall system is addressed by ICC-ES ESR-4652 under defined materials, designs, reinforcement and installation conditions.Attributed to ICON
02A tested ICON load-bearing wall assembly achieved a 178-minute fire-resistance rating under ASTM E119-22 and passed the hose-stream test.Attributed to ICON
03Specified ICON wall assemblies have been evaluated for Florida High-Velocity Hurricane Zone requirements at design pressures up to positive and negative 100 psf.Attributed to ICON
04ICON publishes FormCrete compressive-strength values in approximately the 2,500-to-3,500-psi range.Attributed to ICON
05ICON describes its insulated wall system as providing approximately R-18 thermal performance under its stated configuration.Attributed to ICON

Technical performance depends on the exact wall assembly, material, reinforcement, engineering and project conditions. Final designs require review and approval by the applicable engineers, design professionals and code officials.

04 / Materials

Material coordination, under review.

Layered Construction will coordinate materials within the final project scope. ICON publishes FormCrete compressive-strength values in approximately the 2,500-to-3,500-psi range. Any project-specific material, reinforcement and production decisions require technical review.

05 / Project-dependent potential

Potential benefits — project-dependent

  • 01may serve as the primary load-bearing wall structure
  • 02may consolidate portions of conventional wall construction
  • 03may reduce dependence on conventional wood-framing labor
  • 04may improve production consistency and repeatability
  • 05may shorten the wall-construction portion of the schedule
  • 06may reduce material waste
  • 07durable and energy-efficient concrete construction
  • 08may support architectural forms that may be difficult to achieve with conventional framing

None of these potential benefits is guaranteed. Actual outcomes depend on the exact project, wall assembly, material, reinforcement, engineering, site conditions and scope.
